Title: Improvements in or relating to the catalytic and thermal conversion of hydrocarbon oils to obtain antiknock gaso line
IPC: C10G55/02
Filed: 1942-04-30
Abstract: 561,492. Catalytic cracking of hydrocarbon oils. INTERNATIONAL CATALYTIC OIL PROCESSES CORPORATION. April 30, 1942, No. 5846. Convention date, April 10, 1941. [Class 32] Gasolines of improved anti-knock value and intermediary fractions are obtained by subjecting a straight-run hydrocarbon distillate to catalytic cracking, separating the gasoline fraction from the cracked products of higher boiling range, subjecting these latter fractions to thermal cracking, fractionating the products of the thermal cracking to separate an intermediate fraction from the gasoline and a high boiling residue and subjecting the intermediate fraction to further catalytic cracking the products of which are fractionated to recover gasoline. In modifications (a) the intermediate fraction may be catalytically cracked in the same reaction zone as the straight run distillate ; (b) a heavy residuum stock may be used as starting material in which case it is subjected to a preliminary fractionation to separate the straight run distillate and a heavy residuum which is viscosity cracked with or without reduction to coke ; (c) the gasoline-kerosene fractions isolated in the preliminary fractionation, viscosity cracking, and the thermal cracking stages are subjected to catalytic reforming and the products fractionated together with those from the final catalytic cracking stage. Crude stock is passed through a heater 11 and the heated products fractionated in tower 13 to recover gasoline overhead through a cooler 15, an intermediate fraction collected on tray 14 and heavy bottoms removed through line 33. The fraction collecting on tray 14 is catalytically cracked in coil 18 and drum 20 filled with catalyst ; the products pass to tower 21 where they are fractionated into gasoline recovered over head, intermediate stock collected on tray 25 and a heavy residuum ; the intermediate stock is then thermally cracked in coil 31 the products passing to tower 34 where gasoline is recovered overhead while an intermediate stock is collected in tray 43 and recycled through line 47 for further catalytic treatment in coil 18. The residuum from tower 13 is viscosity cracked in coil 37 with or without reduction to coke in drum 50 and the vaporous, products are passed into the bottom of the tower 34.

Abstract: 194,304. Sauser Akt.-Ges., Assignees of Wydler, H.). March 3, 1922, [Convention date]. Fixed-chamber apparatus for liquids; valve systems for; varying quantity measured in; with counting apparatus.- The three-way valve controlling the filling and emptying of the measuring chamber is fitted with a catch adapted to retain the valve in the position for filling and be released by the pressure of liquid when the chamber is full, allowing the valve to be turned to the emptying position either by hand or automatically by a spring. As shown, the valve is in the position for filling the measuring chamher 3, which is fitted with a float air-valve 1 and capacity-regulating device 2; in this position a spring-pressed catch 6 snaps into a groove in a ring 7 fixed to the handle 8 of the valve so that the handle cannot be moved. When the rising liquid closes the air valve the increased pressure moves a diaphragm 5 to which is fixed a bolt abutting against a catch 6, so as to lift the catch out of the groove and allow the valve to be turned by a spring 11 to the position for emptying through a spout 9. The torque exerted by the spring 12 can be regulated bv turning a member 28 fixed by a grub-screw 29 ; this spring can be dispensed with and the valve turned back by hand. A spring 11 keeps the valve on its seat, and means may be provided for collecting leakage from the valve and returning it to the supply tank. A counter 4 is connected to the catch 6 so as to register the number of deliveries. Instead of the air-valve, a number of capillary tubes leading to an overflow pipe may be used to give the required increase of pressure within the chamber.

Title: Foamable polystyrene and process for moulding it
Inventor: EAGLETON SIDNEY DOUGLAS
IPC: C08J9/00
Filed: 1963-02-14
Abstract: Foamable polystyrene particles consisting of polystyrene, a volatile hydrocarbon blowing agent and from 0.1 to 10% of a wax by weight of the polystyrene are produced by a process in which the wax is incorporated before or after the polymerization of the styrene.  The preferred hydrocarbon is pentane in amounts of up to 10% by weight of the polystyrene. Suitable waxes are those having a melting-point less than the softening point of the polystyrene, e.g. beeswax, paraffin wax, ozokerite, carnauba wax, microcrystalling wax and especially polyethylene wax.  The wax may be incorporated by steeping polystyrene particles containing blowing agent in a molten wax, but a preferred method is to coagulate an aqueous dispersion of a wax in the presence of the foamable particles at a temperature above the melting-point of the wax if necessary under pressure.  The wax may also be incorporated during the later stages of the suspension polymerization of styrene, the blowing agent being added during or after polymerization.  Heating of the foamable particles may be by steam, hot water or hot air, or by an infra-red heater to produce foamed beads which are exposed to the atmosphere for a day or two before moulding. The moulding takes place by injecting steam through inlets in the mould walls to produce a foamed article which requires a cooling time between 30% and 80% of the time necessary when ordinary polystyrene particles containing blowing agent only are employed.

Title: Process of and apparatus for the manufacture of diammonium phosphate
IPC: C01B25/28
Filed: 1930-02-25
Abstract: In the production of diammonium phosphate by neutralizing phosphoric acid with ammonia in two stages, the amount of ammonia absorbed in the first stage by the boiling acid being equivalent to more than one molecule per molecule of acid but not more than can be substantially absorbed, the absorption of the complementary amount of ammonia necessary to cause separation of the salt takes place at a temperature of about 60 DEG -70 DEG  C.  Between two-thirds and three-quarters of the ammonia necessary may be absorbed in the first stage, the neutralization being completed in a second saturator.  Air is blown into the saturators to stir the contents and to eliminate the heat generated, the air and steam from the first saturator being used to preheat the mother liquor from the separation of diammonium phosphate, which is then mixed with phosphoric acid and sometimes water, for example part or all of the condensate from the heat exchanger, and fed to the first saturator.  The phosphoric acid either before or after the above dilution is used to absorb the ammonia escaping from the second saturator.

Abstract: 512,469. Rotor driving arrangements. DELAPLACE, A. March 1, 1938, No. 6368. Convention date, March 3, 1937. [Class 35] [Also in Group XXIV] In a motor gear unit with the motor and sun and planet gear coaxial, one pinion of the gear is arranged so that the motor rotor initially rotates freely and the load is subsequently coupled thereto by wedging members interposed between a sleeve having inclined surfaces and a drum carrying the said pinion, the position of the wedging members being controlled by members movable with the rockable motor stator. In the form shown, the rotor 7 is on a sleeve 9 having a flange 10 carrying planets 11, 12 of unequal tooth number meshing respectively with a pinion 13 on a drum 14 and a pinion 15 on the load shaft 5. Inside the drum is a flanged sleeve 1 with inclined surfaces 16 engaged by wedging members 17, Fig. 4, the position of which is determined by members 19 secured to the stator casing. The sleeve 1, is keyed to a bushing 3 having an extension subjected to the action of a spring (not shown). When the motor is first energised the pinion 15 is held stationary by the load resistance but the planet 11 rotates the drum 14. As the rotor accelerates the reaction causes the stator to rock, the members 19 then allow the wedges 17 to engage the drum 14 and the bush 3 is rocked until the spring pressure is equivalent to the load resistance, the pinion 13 then being held stationary and the drive transmitted through pinion 15. When the motor stops a counterweight (not shown) urges the stator back to its normal posiion and the wedges 17 are thereby enabled to return to their disengaged positions.

Abstract: 230,987. Chance Bros. & Co., Ltd., Alexander, A. H., and Ritchie, M. C. March 12, 1924. Mantle supports and accessories.-In apparatus in which a broken incandescent mantle is automatically replaced by a sound one, inverted mantles c are detachably mounted on levers b, pivoted on radial arms a on a rotatable boss w, connected by bevel wheels w', x, a spindle p, and a spiral spring q with a spindle o, which is rotated by a spring-clockwork mechanism m when a pivoted lever f having a refrac'tory end e, held against the underside of the upper operative mantle by the weight of an attached arm h, is rocked by the fracture of the mantle. The movement of the lever disengages the arm h from a vane i of the air brake or regulator of a spring-clockwork mechanism j, which rotates a face cam k adapted to press aside a spring-pressed lever l carrying the catch-piece n of the mechanism m. During the initial rotation of the spindle o, a cam r acting on a projection s pulls down a slide t and releases a bolt v from the boss w, and the broken mantle is lowered clear of the burner nozzle d by means of a pivoted link 11 carried by a radial arm 10 on a boss 9, mounted on a crank-pin 8 on a spindle 7 passing through the shaft carrying the boss w and connected through a face wheel 6, a pinion 5, a spindle 4, and pinions 3, 2, y to the spindle o. The next mantle slides along an inclined projection 12 on the lever f and depresses it so that the arm h arrests the mechanism j, and the lever l arrests the mechanism m, immediately after the crankpin 8 has caused the lever b to raise the mantle into contact with the burner d, the bolt v engaging the boos w under the action of a spring u. The Provisional Specification describes also a construction in which a counterbalanced lever is released by a breaking of a mantle and releases a motor, which releases a hinged catch lever from a stop on the mantle carrier, which is rotated by a weight or other means. The mantle carrier comprises a rotatable ring, or system of radial stems, or an endless chain, and the mantle ring or holder is provided with a peg, or pegs, for engaging a fixed cam, or cams. to move it, relatively to the carrier, into contact with the burner.
